Property summary
AI-generated overview
The property is a first-floor office suite within a building located in a B1 zone, historically used as an attorney’s office and configured to support professional business uses. The suite includes a large reception area with a waiting area and two desks, two ceramic-tile handicap-accessible bathrooms (men’s and women’s), and a kitchen equipped with cabinets, a sink, and a microwave. A hallway leads from the reception area to a large office with built-in bookshelves; this office is suited to be divided into two offices. The suite also features a corner conference room with multiple windows, a smaller windowed room near the front hall that has been used for storage and files, and a second egress door located between the largest office and the conference room. Finishes include wall-to-wall carpeting, with some newer windows. The parking lot accommodates at least eight vehicles.
